WEFT STOPlVlOTlON FOR LOOVIS.

SPECIFICATION forming part of Letters Patent; No. 298,917, dated May 20, 1884.

Application filed July 2S, 1852. (No model.)

'o aZZ whom it may concern:

Be it known that I, FREDERICK 0. TUCKER,

v of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in "Weft Stop- Motions for Looms; and I do hereby declare that the following is aV full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, refer- Vence being had to the accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts. y

My improvement relates toa mechanism to be placed upon looms for the purpose of stopping the machine whenever the weft-thread breaks, or for any other reason is absent, and fails to pass through the warp.

The object of my invention is to provide a simpler and cheaper device than has heretofore been used for the above purpose.

In the accompanying drawings, illustrating my invention, Figure 1 is a perspective view of part of the lay and breastbeam of a loom provided with my improved stop -motion.

Fig. 2 is a front view of the part ofthe stopmotion attached to the lay, showing also portions of devices attached to the breast-bea1n.

A is the lay.

B is the breast-beam.

C is an arm extending from the breast-beam toward and' under the lay,to support the carn which raises the feelers.

D is a metallic frame secured to the lay for containing the working parts of the stop-motion. This is attached to the front and under sides of the lay, as shown in Fig. l.

E E are the feelers. They are shown in Fig. l raised in about the position in which they remain when the weft-thread is present, and in Fig. 2they are down in the position when the weft-thread is absent, and the loom will be stopped. is shown at WV in Fig. l.

F is a block to which the feelers are attached in the customary manner. It is pivoted to a projection, D', upon the frame D.

Gis a vertically-moving bar, the upper end of which is pivoted to a crank-pin, F', upon the block F. The lower end of bar Gis forked, and each of the two parts passes separately through socket-bearings in the frame D. These two parts are shown at G' and Gl in cam H and raises the feelers.

touching it.

The position of the weft the drawings. The part G' is operated by a cam, H, upon the arm C at each rearward movement of the lay, so that as the lay moves Vhen the feelers are raised, this branch ofthe bar G does not reach down far enough to touch the lever J. The cam H and the lever J are both attached to the arm C-the former by the bolt H', by which the cam can be set in any desired position, and the lever J by means ofthe pin J', upon which it turns horizontally.

K is a connecting-rod reaching from the lever J to the rocking bar L, which enters into a clip, M, screwed to the bar N, for shifting this bar endwise to stop the loom. The bar N operates to stop the loom in any of the customary ways. It may be provided with a fork, as shown in the drawings; or it may release a shipping-lever in the usual manner.

The operation of my invention is as follows: At each backward movement of the lay the end of the bar C' rises upon the surface of the When the lay moves forward, if the weft-thread is present, the feelers are held up by it, and the end of the bar Gr2 passes over the lever J without If, however, from any cause,the Weftthread is absent,the falling of the feelers down into the slot in the top of the lay allows the end of the rod G2 to descend and encounter the lever J, which is then moved, and the bar N is shifted to stop the loom.

Vhat I claim as my invention is- The forked bar G, in combination with the feeler-block F, the feelers E, the cam H, the

lever J, the frame D, and the arm C, said bar and feeler-block being connected to the frame D, adapted to be attached to the lay, and said cam and lever being connected with the arm C, adapted to be attached to the breast-beam or other stationary part of a loom, substantially as described.
